Bravely Default Series

Long story short, im at the point of nearly finishing Bravely Second, and im farting around because of course i don't want it to end. I came upon a side quest in which i have to defeat a Yokai, but in the process she gives me a huge backstory to the series. In all this side quest, "Beware the Eye of Foundar" keeps coming up. Yes ive googled it and no one seems to know what the deal is.

Anybody come across this? My theory is maybe Yokai IS the eye. I don't know, but wow what a great couple of games this has been.
